Dbnald L Spender XHW Patented Feb. 15, 1949 COMPOSITE BOTTLE CAP Donald L. Spender, Naugatuck, Conn, assignor to Scovill Manufacturing Company, Waterbury, Conn, a corporation of Connecticut Application March .6, 1947, Serial No. 732,676

This invention relates to bottle caps particularly of the type used on cologne or perfume bottles. One of the recent trends in the manufacture of bottle caps of this character is to make the cap considerably enlarged in size as compared to the neck of the container to which it is to be attached, and also to have the outside surface of the cap finished in a highly ornamental and polished character.

It is one of the objects of this invention to construct a. bottle cap in which the exterior ornamental shell is removed a considerable distance from the neck of the bottle to which it may be attached. This is accomplished by the use of a filler member of relatively cheap material and construction and having an insert shell slip-fitted into the filler member, which insert shell is provided with suitable means for making detachable engagement with the bottle neck.

A further object is to provide a novel means for securing the insert shell within the filler member by specially shaped lugs that permit ready slip-fit assembly of the attaching shell into the filler member but will not allow it to be axially removed therefrom or rotated therein.

Other objects and advantages of the invention will be pointed out in the detailed description thereof.

Referring now to the drawing, in which:

Fig. 1 is a vertical sectional view taken through a composite bottle cap construction embodying my invention.

Fig. 2 is a bottom plan view of the same. I

Fig. 3 is a side elevational view of the interior insert attaching shell, per se. 1

Fig. 4 is an enlarged fragmentary sectional view taken along the line 4-4 of Fig. 3 made on an enlarged scale to clearly show up the particular features of the locking lug construction, and

Fig. 5 is a fragmentary horizontal sectional View of the lug construction with the view being taken along the line 55 of Fig. 4.

Referring now to the drawing for a, detailed description of the parts, the numeral l0 designates an outside cupped shell which may be embossed or highly polished so as to embody all the ornamental features that the user may desire in association with the containers to which it is attached. In this case the shell ii) is shown to be a smooth cylindrical cupped shell.

Fitted within the shell I0 is a cupped shaped filler member II which is secured in place by an interposed film of cement or adhesive material shown by a heavy line in Fig. l and designated l2. The axial length of the filler member is 4 Claims. (Cl. 215-43) preferably made slightly less than the length of the cupped shell Ill so that its exposed annular edge I 3 is removed a slight distance from the edge of the shell in and thus provides for a depending skirt id as a part of said shell Ill for appearance sake. The filler member II is preferably made of Wood, as conventionally shown in Fig. 1. Wood is selected for this member as it is relatively cheap and readily adaptable to fit the needs of manufacturing a composite cap of the character involved. It should be understood, however, that other materials could be selected for this member, as for instance from the numerous molded plastics having like characteristics to a wooden member.

In order to provide a removable attachment for the composite cap with the conventional threads formed on a bottle neck, an attaching insert shell i5 is designed to have a slip-fit or telescopic assembly into the hollow part of the wooden filler member II with its inner closed end It abutted against the base end Ha of the wooden filler member II. The attaching insert shell l5 is provided with a rolled thread in its cylindrical wall as a means for detachable engagement with the threads usually formed on the neck of bottle containers. 7

Since considerable torque and axial stress will be imposed upon the insert shell l5 of my composite cap when applied to a container, it is necessary to provide adequate means to anchor the insert shell l5 in the wooden filler member I I. To this end use is made of special shaped lugs l8 sheared and formed out of the side walls of the insert shell l5 and capable of being sprung inwardly to allow the insert shell l5 to be easily telescoped within the hollow of the wooden filler member H. The inherent tendency for the lugs l8 to spring outwardly because of their initial outward forming will cause them to embed into the material of the filler member I I and to increase the bite of the lugs l8 into the material when any force is exerted upon the attaching shell I5 to withdraw it out of the wooden filler member l'l.

As clearly seen in Figs. 1, 4 and 5, I employ three equally spaced lugs l8 which are formed in the crown surface of the rolled thread I'll Describing the lugs in detail, each lug is sheared for its entire length out of the metal stock of the side wall of the insert shell [5 and integrally connected at its upper end to the threaded portion of said shell l5. The lugs l8, as best shown in Fig. hare made of arcuate shape in an axial direction with the concave part disposed inwardly toward the axis of said insert shell l5, and also made arcuate shaped in the horizontal transverse section as seen in Fig. 5 with the concave part disposed outwardly. This latter formation is resorted to for considerably increasing the strength of the lugs l8 and provides for a pair of opposed wings l9 that are adapted to.v slide over. the interior;- wall," ot the; filler member II when the insert shell I5 is being assembled in place.

The normal position of the lugs to the shell l5i is initially biased outwardly from the. crest of. the threads ll, i. e. prior to the assembly of 'said shell l5 into the filler member: H: Therlugs; [8,; are constructed, however, sonthat they. cambesprung inwardly during the telescoping opera-- tion of the insert shell [5 into -the-.filler;memb.er and will spring out into the wooden filler when completely assembled in a manner such as shown in Fig. 1. It will be obvious from the specific structure-of the lugs: l8; that the more the axialforcesimposed:uporrthe-insert shell. l5 to with-- draw it: from the wooden filler'member H the. more: deeply will the: lugs lBwbe-causedto bite into: said filler:to hold said; insert shell I5: in a permanent secure. position.
